Kha-Beleth (also known as the Demon Sovereign) is the main antagonist of Heroes of Might and Magic V and the undisputed leader of the Demon race in Ashan, who has ruled the jailworld of Sheogh since the disappearance of the Six Demon Overlords in 564 YSD. Enigmatic in his ways yet ineffably evil, his ambition to secure victory in the name of Urgash and resultant schemes define the events of Heroes V and, later, Dark Messiah of Might and Magic.
